JUSTUS-LIEBIG- UNIVERSITÄT GIESSEN Institut für Angewandte Mikrobiologie Impact of Fermented Organic Fertilizers on in-situ Trace Gas Fluxes and on Soil Bacterial Denitrifying Communities in Organic Agriculture Dissertation zur Erlangung des Doktorgrades der Naturwissenschaften (Dr. rer. nat.) dem Fachbereich Agrarwissenschaften, Ökotrophologie und Umweltmanagement und der Gemeinsamen Kommission Naturwissenschaften vorgelegt von Kristina Schauß Giessen, im Juli 2006 For my Family Acknowledgements First of all, I like to thank my supervisor Prof. Sylvia Schnell for giving me the opportunity to work on this project in her lab. I enjoyed being a part of your group and greatly appreciate your confidence in me, the fact that your door was always open to discuss my project and other things, the possibility to attend international conferences, especially overseas, and your support over the years, particularly in difficult times… I also like to thank Prof. Hans-Jürgen Jäger for agreeing to review my thesis. Special thanks to my advisor Dr. Stefan Ratering for introducing me to the ins and outs of gas chromatography; it was very reassuring to have someone at hand familiar with its various quirks!
